A random rash appeared on my back and shoulders and partially on my forearms but it does not appear to be on my chest, neck, stomach or anywhere on my lower bottom. It s extremely itchy and only becomes obviously noticeable after a hot shower or if I put lotion on it (at first I thought it was a dry skin rash). I am a recently finished ALL Leukemia treatment individual as well. I have not changed much in my routine except in October I started a new detergent for clothes, however the symptoms didn t really start until mid November. If it were this-- wouldn t it be on my chest and legs aswell? Any explanation?
